I think that I got this pretty much right the first time - it's a wonderful patchwork of colours, ideas and human drama (not to mention a great source of conceptual shorthand for signifying various facets of existence and everything.
(Was inspired to rewatch by Icelander, with which I think Huckabees has a fair bit in common - not least in the prominence that both accord to a pair of existential/philosophical detectives - though Long's novel is more open-ended and unresolved, which may or may not be the particular prerogative of literature.)
